Hello, have a 850er 12/96 with 2 liters 10 valve motor. Wanted to read out the fault memory and bought me the 2 repair manual books (Bd. 1290 German and English by Haynes ). It is spoken everywhere of a box next to the motor electronics, which is with LED flashes etc. and reset button that should make this possible. In my 850er there is not this box. There is only the engine control unit of Siemens in it. Nothing else. I found an OBD II plug in the passenger compartment, where such a usual way is, also icht. Can someone tell me how this is regulated with the model. The books are scrap if they do not even show something. grüße wolfi
